I have been trying to build c++ boost to work with qt creator but until now all what i get is undefined reference to different things things so here is what I did so far:-
I build c++ boost by running bootstrap.bat then bjam
I include the path in my qt creator .pro project
like this
QT += core gui
TARGET = Heap
TEMPLATE = app
INCLUDEPATH += C:\boost\boost_1_48_0
LIBS += -L"C:/boost/boost_1_48_0/stage/lib"
SOURCES += \
main.cpp
HEADERS += \
clss.h \
inputstream.h \
outputstream.h \
myexception.h \
heaptest.h \
comparable.h \
heap.h
FORMS +=
here is my sample code I am testing on
#include <boost/regex.hpp>
#include <iostream>
#include <string>
int main()
{
std::string line;
boost::regex pat( "^Subject: (Re: |Aw: )*(.*)" );
while (std::cin)
{
std::getline(std::cin, line);
boost::smatch matches;
if (boost::regex_match(line, matches, pat))
std::cout << matches[2] << std::endl;
}
}
and here is the compilation error I get

Error while building project Heap (target: Desktop)
When executing build step 'Make'
How can I get this to build?
Try changing the LIBS += -L"C:/boost/boost_1_48_0/stage/lib" line to:
LIBS += -L"C:/boost/boost_1_48_0/stage/lib" -lboost_regex
(replace boost_regex with the actual name of the built library (which will probably be something like boost_regex-mgw44-mt-1_48))

I'm trying to use SWIG so that I can call C++ code from Go.
I want to use SWIG so that it can generate me wrapper code. The C++ code in question is generated by the protobuf compiler.
I have two hello.i files hello.i and protobuf.i:
protbuf.i
#define GOOGLE_PROTOBUF_VERSION 3021008
#define GOOGLE_PROTOBUF_MIN_PROTOC_VERSION 3021000
hello.i
%module example
%include "protobuf.i"
%{
#include "hello.pb.h"
#include "hello.gen.h"
%}
#include "hello.pb.h"
#include "hello.gen.h"
namespace example {
void handle_Person(example::Person& m, unsigned char* friends);
}
I am able to compile this with the SWIG command swig -go -cgo -c++ hello.i and it generates Go and _wrap.cc file.
Then I create a shared library with the following sequence of commands:
g++ -fPIC -c hello_wrap.cxx hello.pb.cc hello.gen.cc -ldl -lprotobuf -lprotoc -L${MY_PROJECT}/protobuf -L${MY_PROJECT}/protobuf/third_party/abseil-cpp/absl -L${MY_PROJECT}/protobuf/third_party/utf8_range
g++ -shared -o libhellowrap.so hello_wrap.o hello.gen.o hello.pb.o -ldl -lprotobuf -lprotoc -L${MY_PROJECT}/protobuf -L${MY_PROJECT}/protobuf/third_party/abseil-cpp/absl -L${MY_PROJECT}/protobuf/third_party/utf8_range
Now I want to use this in Go so I create a main.go file:
package main
/*
#cgo CFLAGS: -I/my_project/example
#cgo LDFLAGS: -L/my_project/example -lhellowrap -ldl -lstdc++
#include <stdlib.h>
*/
import (
"C"
"fmt"
"my_project/example"
)
func main() {
var p example.SwigcptrExample_Person
p = example.SwigcptrExample_Person(uintptr(int32(2000)))
friends := make([]byte, 5)
example.Handle_Person(p, &friends[0])
fmt.Println("New Friends: ", friends)
}
Then I run this main.go file and the following linkage errors occur:
# command-line-arguments
/usr/local/go/pkg/tool/linux_amd64/link: running g++ failed: exit status 1

I have various things when trying to solve this problem but it feels like I'm missing a crucial step.
I am cross-compiling OpenCV libraries (2.4.9) and Raspicam (0.1.3) in Eclipse CDT IDE for Raspberry Pi. I am trying to compile a basic application that looks as the following:
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/opencv.hpp>
#include <raspicam.h>
#include <raspicam_cv.h>
using namespace std;
using namespace cv;
int main()
{
....
namedWindow(output_window_name, CV_WINDOW_AUTOSIZE);
namedWindow(grayscale_window_name, 100);
namedWindow(thresholded_window_name, 100);
namedWindow(contours_window_name, 100);
moveWindow(grayscale_window_name, 20,20);
moveWindow(thresholded_window_name, 20, 250);
moveWindow(contours_window_name, 20, 600);
vector<int> compression_params;
compression_params.push_back(CV_IMWRITE_JPEG_QUALITY);
compression_params.push_back(100);
raspicam::RaspiCam_Cv Camera;
....
}
To compile I made sure that libopencv_*.so files are in the cross compilation sysroot and linked in Eclipse using -l flags such as -lopencv_core -lopencv_highgui etc. I also included every include/ folder in sources using -I flag in Eclipse Build Settings.
Inclusion using #include and namespace declarations do not result in any errors.
Target building looks like this in the console:
arm-linux-gnueabihf-g++
-L"C:\SysGCC\Raspberry\arm-linux-gnueabihf\sysroot\usr\lib"

This indicates that I have two type of errors.
1-) undefined reference (for functions)
2-) undefined reference to vtable` (Related to virtual functions I believe)
In order to overcome this problem, I feel like I have to change STL/C standards, but do not know what to do exactly. Also, the fact that libraries are compiled and included correctly but there are still undefined references is really weird to me.
Any guidance regarding how to solve this problem is greately appreciated.
Thanks in advance.
I am new to using CImg and boost. I am getting undefined symbol references as mentioned below, in the code also shared below.
I am using this command line to build it: g++ -lboost_filesystem -lboost_system -L/usr/X11R6/lib -lm -lpthread -lX11 grayscaleConvertor.cpp &> errLog.txt
I am using the -l args in the compiler command. eg: -lboost_filesystem which I read on another post in stackoverflow, but that is not helping resolve the boost::filesystem:: symbols
locate CImg : /usr/include/CImg.h
locate boost: /usr/include/boost (plus more lines)

Compile instruction look like this:

I downloaded and install latest source code from Intel.Also I already use -ltbb and -std=c++11 at compile time and I include tbb files inside my code. I can't figure out the problem so far. Does anyone face anything like this before with Intel TBB? I am assuming that is something with the linking of library but I can't figure it out
Try to insert "-ltbb -std=c++11" just before -o and it should work!
Patroklos Patroklou's answer didn't help, so I put -ltbb at the end of my command and it worked.

The directory /opt/Informix/11.5FC8/lib/c++ is listed in LD_LIBRARY_PATH. Can anyone help me to get rid of these errors?
You are not actually linking with the library using the -l command line parameter. The -L command line parameter tells the linker where to look to find it, but you don't specify the actual library.
Also LD_LIBRARY_PATH is used during runtime, but a better way to configure a non-standard directory is to configure the dynamic linker using /etc/ld.so.conf or a file in /etc/ld.so.conf.d/.
